I have version 3.0 of the chalk dispenser system sitting in my living room now.
The small boxes marked “RED CHALK” conveniently fit into the 3” opening on the top. They sent us some empty boxes to put the Boomerite in. The Boomerite will go in first and be exposed to gun fire through the 1.5” hole in the front.
This version also has 1/4” armor plate on the face. This should withstand the bullet impacts much better.
Ry plans to be back in Idaho on Saturday and we will visit the Boomershoot site to do our tests. The weather forecast on Saturday is for a low of -1 F and a high of 15 F. We had a blizzard last night and today and it put down several inches of snow. This may complicate things some. I’m not sure we will be able to drive all the way out to the Taj Mahal to mix the Boomerite. I may have to walk or snowshoe in, mix it up, and carry it back while Ry preps the target at the shooting berm.
